Brachythemis impartita, the Northern banded groundling, is a species of dragonfly, a skimmer from the family Libellulidae from central and northern Africa, its range extending into southern Europe and the Middle East. It was previously considered to be conspecific with B. leucosticta.
Brachythemis impartita has a pale cream pterostigma in both sexes and their eyes appear to be striped. The female has a buffy abdomen and thorax, males are darker and mature males can be dark blue to black on the abdomen and thorax. Males have bands on the outer wings from the node to just short of the pterostigma, this is paler in teneral individuals but darkens as the dragonfly matures. Where they overlap with B. leucosticta the males can be distinguished by the colour of the veins and the genital lobe, as well as by the ventral structure of segment 8. The females cannot yet be told apart. The length of this dragonfly is from 25 to 34 millimetres (0.98 to 1.34 in) and the span of the hindwings is 20 to 26 millimetres (0.79 to 1.02 in).
Brachythemis impartita is found from central Africa as far south as the Democratic Republic of the Congo and Tanzania north through... Wikipedia →

Possible
About 20% of wildlife watchers report a Northern Banded Groundling sighting in Cairo on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 38 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and July
In those months about 40% of wildlife watchers report a Northern Banded Groundling in Cairo on a given day, against under 5% in August–September and November–March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Northern Banded Groundling sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Northern Banded Groundling sightings, Cairo ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Accra (Ghana, about 20%).
Same family: Libellulidae
The closest relatives of the Northern Banded Groundling that you can see in Cairo (family Libellulidae, Skimmers) are Violet Dropwing (about 20%) and Wandering Glider (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Northern Banded Groundling is recorded against all the insects logged in Cairo (14 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
